Referring to FIGS. 1 and 2 , the fanless exhaust device 100 according to the first embodiment of the present invention includes a main body 110, a wind path interference preventing unit 120, a first fan 130, and A second fan 140 is included.

As shown in FIGS. 1 and 2 , the main body portion 110 has a wind path interference prevention unit 120, a first fan 130, and a second fan 140 installed on each side of a hexagonal body or the like. As a connecting frame, openings are formed on the front and rear and top, bottom, left and right surfaces.

Moreover, the main body portion 110 has a first suction port 112 formed on the front side, which is the opposite side fixed to the wall w, and the upper, lower, left and right suction ports 113 on the side of the first suction port 112 are Each is formed, and second intake ports 114 are formed on the rear surface in the direction of the fixing surface of the wall W, respectively, and the first fan exhaust port 118 a is formed by the spacing of the spaced path interference preventing parts 120, The entire exhaust port (118 c) is formed to be connected to the wall (w) to exhaust air containing contaminants on the rear side to the outside.

Here, the upper, lower, left, and right inlets 113 draw air around them according to Bernoulli's principle when the first and second fans 130 and 140 are driven. Air is sucked in through the cotton, and the intake is improved.

At this time, the first inlet 112 and the second inlet 114 are passages for inhaling contaminants such as smoke, smell, and polluted air generated in factories, large buildings, and indoors such as subways.

In addition, the partition walls 116 spaced apart from the upper and lower surfaces of the body portion 110 are spaced apart from the inside of the body portion 110 to the upper and lower sides so that the second fan 140 is installed in a buried state therein.

Moreover, the bulkhead 116 has a wind speed of 1-nearly 0 in which the wind sucked through the second fan 140 moves.

Here, the barrier rib 116 is illustrated as being provided on the upper and lower sides of the inside of the body portion 110, but is not limited thereto and may be provided on the left and right sides of the inside of the body portion 110.

The wind path interference prevention unit 120 is provided inside the main body 110 so that the wind path of the first fan 130 and the wind path of the second fan 140 do not interfere with each other, so that the second fan (140) to control the wind path.

At this time, the wind path interference prevention unit 120 is provided with a guide 122 bent at an end so that the direction of the wind introduced from the second inlet 114 by the guide 122 is changed to the first fan (It is reversed so that it is not affected by the wind path of 130.

Therefore, the wind path interference prevention unit 120 is formed in a vertical straight direction, and the guide 122 is formed in a horizontal direction.

As shown in FIGS. 1 and 2 , the first fan 130 is installed on the side of the first inlet 112 and rotates in the transverse direction to suck indoor air through the first inlet 112.

As shown in FIGS. 1 and 2 , the second fan 140 is installed in a state buried inside the second inlet 114 and rotates in the longitudinal direction through the second inlet 114 to remove indoor air. inhale additionally.

At this time, the first and second fans 130 and 140 are driven by motors (not shown in the drawings).

Moreover, in the case of the first fan 130 and the second fan 140, in the case of the conventional method, the capacity (number of rotations, etc.) of the first fan 130 is greater than the capacity (number of rotations) of the second fan 140 Although it should be small, since each path is not interfered with by the wind path interference prevention unit 120, the capacity of the first fan 130 can be greater than the capacity of the second fan 140. In this way, the first fan (130) is larger than the capacity of the second fan 140, so it is possible to suck a lot of wind.

As described above, in the exhaust device 100 according to the first embodiment of the present invention, the first fan 130 and the second fan 140 are rotated by the driving force when power is applied.

At this time, pollutants generated in the room are sucked through the first inlet 112 by the first fan 130 and the second inlet 114 by the second fan 140, and the sucked air is passed through the entire exhaust port (118 b) is forcibly exhausted.

In addition, when the first and second fans 130 and 140 are driven, the air pressure is lowered by Bernoulli's principle and the air around the first inlet 112 and the upper, lower, left and right inlets 113 is drawn. 1 Air is sucked through not only the inlet 112 but also through the top, bottom, left and right surfaces, so the intake amount is improved. And when the second fan 140 is driven, it is sucked in by the wind exhausted through the second exhaust port 118 b and pushed to be discharged together with the wind of the first fan 130, and at the same time by the path interference prevention unit 120 Since it moves without interference, it is possible to improve the suction efficiency by increasing the capacity of the first fan 130.

Therefore, according to the Bernoulli effect, air is sucked from the rear and top, bottom, left and right sides of the main body 110 by the first and second fans 130 and 140, and the main body 110 through the second fan 140 Even if air is sucked from the upper and lower sides of the first fan 130 and strong air is injected by the first fan 130, the first fan 130 and the second fan 140 have no resistance to each other, so the maximum suction of the first fan 130 You can get 2˜3 times the effect than the existing fan.

Referring to FIG. 3 , the fanless exhaust device 200 according to the second embodiment of the present invention=main body 210, wind path interference prevention unit 220, first fan 230, and second fan 240, and unlike the previous embodiment, only the structures of the partition wall 216 and the wind path interference prevention unit 220 are different, so only the different parts will be described in detail.

The bulkhead 216 is formed with an inclined end located on the side of the wind path interference prevention unit 220, unlike the previous embodiment located in the horizontal direction.

And since the end of the wind path interference preventing part 220 is also formed inclined to be parallel to the inclined portion of the bulkhead 216, the direction of the wind sucked through the second fan 240 is not vertical but inclined when discharged turn on

In this way, when the wind sucked from the first fan 230 by the inclined portion of the wind path interference prevention unit 220 passes through the circle 1 exhaust port 218 a whose inlet gradually narrows, the pressure increases will move at high speed.

And since the second fan 240 is rotated relative to the longitudinal axis, it is preferable to install it on the side of the circle 1 exhaust mechanism 218 a. 1451 On the other hand, although not shown in the drawing, the wind path interference prevention unit 220 and the guide 222 may also be provided so as to be able to adjust the angle as in the previous embodiment.

Here, the unexplained numeral 212 denotes the first inlet, 214 the second inlet, 218 a the fan exhaust, and 218 b the entire exhaust.

It is deformed when rotated by the wind, and restored when the wind is not blowing. 1491 Meanwhile, the rotation angle of the wind direction guide piece 1162 of the torsion spring 1164 varies according to the strength of the wind. That is, when the wind blows weakly, the angle of the wind direction guide piece 1162 decreases, and when the wind blows strongly, the angle of the wind direction guide piece 1162 increases.

Moreover, the angle limiting protrusion 1163 protrudes from the inner wall surface of the wind path interference preventing part 120 so as to limit the maximum rotation angle of the wind direction guide piece 1162.

Therefore, the wind direction guide part 138 is provided to have a right angle with one side wall of the heat dissipation part 130 when there is no wind, and when wind blows, it rotates at the maximum angle to guide the wind toward the outlet 114. do.

The fan exhaust port 118 a formed between the end of the wind path interference prevention unit 120 and the partition wall 116 is a passage through which air sucked from the second fan 130 passes.

At this time, since the air exhausted through the first intake port 112 and the air exhausted through the fan exhaust port 118 a have different exhaust positions, the first fan 130 rotates at high speed and the second fan Even when the fan 140 is rotated at a low speed, the second fan 140 can suck wind without interference.

And referring to FIG. 5 , the wind path interference prevention unit 120 is provided so that the angle between the end and the guide 122 can be individually adjusted. This structure is also applicable to the second embodiment.

To this end, the wind path interference prevention unit 120 is rotatably provided on the corresponding surface by a rotating shaft in a state of being divided into upper and lower parts 120 a and 120 b, and is a cylindrical column provided at the end of the upper part 120 a. A radial hemispherical groove 1212 is formed on the outer circumferential surface of the shaped protrusion 1210.

In the lower part 120 b, a sphere 1220 is provided on a surface adjacent to the protrusion 1210 in a state of being elastically supported by the elastic body 1230, so that the sphere 1220 is formed in the radial hemispherical groove 1212. When coupled to either one, the angle of the lower part 120 b is fixed, and the lower part 120 b is further rotated so that the sphere 1220 is separated from the hemisphere groove 1212 and rotates while moving to the adjacent hemisphere groove 1212. angle is adjusted.

Moreover, the guide 122 is also provided rotatably by the rotating shaft on the corresponding surface with the lower portion 120 b, and has a cylindrical shape provided at the end of the upper portion 120 a.

Radial hemispherical grooves 1212 are formed on the outer circumferential surface of the protrusion 1210.

A radial hemispherical groove 1212 is formed on the outer circumferential surface of the cylindrical protrusion 1210 provided at the end of the lower portion 120 b.
